THE YEAR 2014 STARTED OUT WITH SOME OF THE COLDEST AIR IN YEARS AS
ARCTIC AIR SURGED INTO THE REGION ON JANUARY 1 AND PERSISTED FOR
MANY DAYS. PORTLAND SAW 4 STRAIGHT DAYS FALL TO ZERO OR BELOW. THE
COLDEST DAY WAS JANUARY 3 WHEN THE TEMPERATURE DID NOT RISE ABOVE 9
DEGREES. THE COLDEST TEMPERATURE IN 2014 WAS 14 BELOW ZERO ON
JANUARY 4. WHILE BELOW ZERO TEMPERATURES ARE NOT THAT UNCOMMON IN
THIS REGION, IT IS UNUSUAL TO SEE BITTER COLD AND HEAVY SNOW OCCUR
AT THE SAME TIME. NORMALLY WHEN TEMPERATURES GET TO ZERO DEGREES OR
COLDER IT IS DIFFICULT TO SEE HEAVY SNOW DUE TO THE LACK OF MOISTURE
IN THE AIR. HOWEVER, DURING THE EXTREME COLD ON JANUARY 2 AND 3 A
TOTAL OF 11.9 INCHES OF SNOW WAS MEASURED AT PORTLAND. WHILE NOT A
RECORD AMOUNT OF SNOW, IT WAS THE HEAVIEST SNOWFALL OF 2014 AND
OCCURRED DURING THE COLDEST TEMPERATURES OF THE YEAR AS WELL.
THE WINTER COLD CONTINUED THROUGH FEBRUARY AND MARCH. SEVERAL
SNOWSTORMS IMPACTED THE AREA MAKING FEBRUARY THE SNOWIEST MONTH OF
THE YEAR IN PORTLAND. WHILE MARCH WAS NOT AS SNOWY, IT MADE UP FOR
IT IN THE CONTINUED COLD TEMPERATURES. MARCH WAS THE COLDEST IN
ALMOST 50 YEARS AND THE 4TH COLDEST ON RECORD. A RECORD 10 DAYS DID
NOT SEE THE TEMPERATURE RISE ABOVE FREEZING IN PORTLAND IN MARCH
2014. THE RECORD LOW TEMPERATURE OF 11 DEGREES ON MARCH 24 WAS ALSO
THE FIRST TIME A RECORD LOW TEMPERATURE WAS BROKEN AT PORTLAND SINCE
MARCH 6 2007. THE EXTENDED WINTER COLD ALLOWED THE WINTER SNOW PACK
TO STAY ON THE GROUND THROUGH APRIL 7. THE LAST FREEZE OF THE SEASON
WAS ON APRIL 20 WHICH WAS ABOUT 2 WEEKS EARLIER THAN NORMAL.
WARMER WEATHER FINALLY ARRIVED IN MAY AFTER SIX STRAIGHT MONTHS OF
BELOW NORMAL TEMPERATURES. PORTLAND FIRST REACHED 70 DEGREES ON MAY
10 WHICH WAS ABOUT 3 WEEKS LATER THAN NORMAL. THE FIRST 80 DEGREE
ARRIVED SOON AFTER ON MAY 12 WHICH WAS RIGHT AROUND NORMAL. HEAVY
RAIN FELL ON JUNE 13 WITH MORE THAN 2 INCHES RECORDED. MORE HEAVY
RAIN FELL A FEW WEEKS LATER AS HURRICANE ARTHUR PASSED BY OFFSHORE
ON JULY 2 THROUGH 5. THE HEAVY RAINS FROM ARTHUR WASHED OUT MOST
INDEPENDENCE DAY ACTIVITIES.
AFTER A THREE MONTH STRETCH OF SLIGHTLY WARMER THAN NORMAL
TEMPERATURES, AUGUST WAS DOMINATED BY COOLER CONDITIONS. VERY HEAVY
RAIN FELL ON AUGUST 13 WHEN MORE THAN 6 INCHES OF RAIN WAS RECORDED
IN JUST A FEW HOURS THAT EVENING, LEADING TO FLASH FLOODING IN THE
CITY. THIS WAS NOT ONLY A RECORD DAILY RAINFALL BUT ALSO CONTRIBUTED
TO THE SECOND WETTEST AUGUST ON RECORD. WARMER WEATHER FINALLY
ARRIVED BY THE END OF AUGUST WHEN AUGUST 27 RECORDED THE WARMEST DAY
OF 2014 AT 88 DEGREES. THIS FINAL WARM SPELL OF THE SUMMER LASTED
THROUGH THE FIRST PART OF SEPTEMBER BEFORE TEMPERATURES TURNED
COOLER AGAIN.
PORTLAND DID NOT REACH 90 DEGREES IN 2014. ONLY 6 OTHER TIMES HAS
PORTLAND FAILED TO REACH 90 DEGREES, MOST RECENTLY IN 2008. ON
AVERAGE PORTLAND SEES 4.6 DAYS PER YEAR REACH 90 DEGREES. THE YEARLY
HIGH OF 88 DEGREES ON AUGUST 27 WAS THE THIRD COOLEST ON RECORD. THE
FOLLOWING IS A LIST OF THE COOLEST YEARLY MAXIMUM TEMPERATURES AT
PORTLAND.

THE COMBINATION OF HEAVY RAIN IN MID JUNE, HURRICANE ARTHUR IN JULY,
AND THE FLASH FLOODING IN AUGUST, SUMMER 2014 ENDED UP BEING THE 4TH
WETTEST ON RECORD IN PORTLAND. IN CONTRAST TO THE WET SUMMER,
SEPTEMBER ENDED UP BEING THE DRIEST IN 30 YEARS AND THE 12TH DRIEST
ON RECORD.
AS THE CALENDAR CHANGED TO OCTOBER, THE STORY BECAME THE RECORD
WARMTH. IT WAS THE 2ND WARMEST OCTOBER ON RECORD, BUT THE LOW
TEMPERATURES WERE THE WARMEST ON RECORD BY A LARGE MARGIN. SINCE
RECORDS BEGAN IN PORTLAND IN 1941 THERE HAVE ONLY BEEN 5 DAYS IN
OCTOBER WHICH DID NOT FALL BELOW 60 DEGREES. TWO OF THOSE DAYS
OCCURRED IN 2014. THE COLDEST TEMPERATURE OF THE MONTH WAS ONLY 34
DEGREES, ALSO THE WARMEST EVER. AS A RESULT OF THE UNUSUAL WARMTH,
PORTLAND SAW ITS LATEST FIRST FREEZE ON RECORD WHEN THE TEMPERATURE
FINALLY FELL TO FREEZING ON NOVEMBER 3. THIS ALSO MARKED THE LONGEST
GROWING SEASON ON RECORD. THE FIRST SNOW OF THE SEASON FELL ON
NOVEMBER 2, THE DAY BEFORE THE FIRST FREEZE OF THE SEASON. NEVER
BEFORE HAS THE FIRST SNOW FALLEN BEFORE THE FIRST FREEZE. THE TABLES
BELOW LIST THE LATEST DATES OF THE FIRST FALL FREEZE IN PORTLAND AND

NOVEMBER SAW A WILD STRETCH OF WEATHER JUST IN TIME FOR
THANKSGIVING. RECORD HIGHS WERE REACHED ON NOVEMBER 24 AND 25 WHEN
THE TEMPERATURE SOARED INTO THE 60S. BUT HEAVY SNOW BEGAN ON
NOVEMBER 26, JUST IN TIME FOR THE BUSIEST TRAVEL DAY OF THE YEAR.
THE THANKSGIVING SNOWSTORM DROPPED 8.5 INCHES OF SNOW IN PORTLAND
FROM NOVEMBER 26 THROUGH 28, HAMPERING HOLIDAY TRAVEL PLANS. COLD
WEATHER AND OCCASIONAL LIGHT SNOW CONTINUED THROUGH THE FIRST PART
OF DECEMBER WHEN TEMPERATURES SAW A WARMING TREND AGAIN. ALL THE
EARLY SEASON SNOW MELTED BEFORE CHRISTMAS, MAKING WAY FOR THE
WARMEST CHRISTMAS ON RECORD AT PORTLAND.
THE AVERAGE TEMPERATURE FOR THE YEAR WAS 46.3 DEGREES WHICH WAS 0.2
DEGREES BELOW NORMAL AND THE COLDEST YEAR SINCE 2009. THE WARMEST
YEARLY AVERAGE TEMPERATURE ON RECORD WAS 49.2 DEGREES SET IN 2012
